The Mountain Lab Exhale Emergency Bivy Breathable Sleeping Bag is waterproof, windproof and unlike most other emergency blankets and bivi is also breathable. This is a huge benefit for anyone who needs to hunker down and stay warm in cold conditions outdoors.

The Mountain Lab Breathable Bivy is constructed of a four-ply material developed by NASA to breathe effectively yet still reflect 70-90% of a person's body heat. The advanced material is much stronger than a typical lightweight emergency bivy or blanket.

The Breathable Bivy features waterproof seams, a 1/4 side zip for easy entry and a drawstring hood closure to help seal in the heat.
